摘　　要：[目的]探讨复配制剂对茶小绿叶蝉（Empoasca flavescens）的防效。[方法]开展5种复配剂对茶小绿叶蝉的田间药效试验。[结果]5种复配剂对茶小绿叶蝉的速效性较好,药后7 d防效在90%~95%之间,有效控制期14 d左右,且单剂作用机制互不相同,药剂复配可有效克服或延缓抗药性,减少用药量,弥补单剂不足,协同发生作用。[结论]5种复配药剂对茶小绿叶蝉具有良好防效。[Aims] This study aims to investigate the control effects of several compound pesticides on Empoasca flavescens. [Methods] The field experiment of five compound pesticides were carried out. [Results] Five compound pesticides on E. flavescens had excellent quick action withcontrol effect of 90-95% on 7 d after treatment. The effective control time was about 14 d and pesticide mechanism was different from each other, combined pesticides can effectively overcome or delay the development of resistance, reduce dosage, and compensate shortcomings of single pesticide, showing the synergistic effect. [Conclusions] Five compound pesticides were effective for controlling E. flavescens.
